Carnes DA Series Adjustable Slot Diffusers providean economical method to incorporate horizontal orvertical discharge for either perimeter or interior zoneapplication. Superior design makes the DA Seriesexcellent for use in VAV systems. It will hold a

horizontal pattern at less than 10% of nominal CFM(50 CFM per linear foot of slot). When set for verticaldischarge, it provides an air curtain effect along exterior walls and windows.

DESCRIPTION — DA SeriesThe Carnes DA Series Adjustable Slot Diffusers areavailable in one, two, three or four slots for exposedT-bar ceilings. Models are also available for DonnFineline type ceilings. The available slot widths are3/4”, 1” and 1-1/2”. The DA Series Slot Diffuser uti-lizes an adjustable pattern control in each slot to con-trol the direction of air discharge, either parallel withor perpendicular to the diffuser face. The adjustmentfrom the face of the diffuser allows for control in a full180° range for either right or left, horizontal or vertical. The four foot and five foot diffusers have asplit pattern control in each slot. This enables one toobtain both horizontal left and horizontal right air flowfrom a single slot unit. These units are available withinsulated or uninsulated plenums. The insulationused on the one slot units is 1/4” thick 3 pound density. The two, three and four slot units use 1/2”thick 1-1/2 pound density material. All insulation isinternally mounted fiberglass with matte faced to prevent erosion. The insulation conforms to UL 181and NFPA 90A requirements. The DA Series is available with 6”, 8”, 10” or 12” inlets. The duct collaris 1-3/4” deep for ease of flex duct connection.

SUGGESTED INSTALLATION INSTRUCTIONS

Carnes DA Series Adjustable Pattern Slot Diffusersare designed for use in most standard exposed suspended grid systems. The Model DASC two slotstraddles the main T-bar and is supported by T-barson the diffuser perimeter. The Model DASC one slotis supported on one side by the main T-bar and onthe other side by an additional T-bar. Models DARCand DAMC have center T-bars as part of the unit sothey are installed in the same method as the Model

DASC one slot.In order to maintain color continuity all required additional T-bars are by others. Although support isprovided by the T-bar, additional support may beadvisable. Supply units are provided with a wire support screw in each end of the diffuser plenum.These can be used to connect wire supports from theT-bar or from structural support.

Carnes Matched Fixed Pattern Slot Diffuser and Return Air Slot

Model DFSB — Supply Model DFRB — Return

Features

�� Eliminates drafts. Maintain horizontal air flow at levels below 10% of nominal CFM (50 CFM per

linear foot of slot.

�� The diffuser, in conjunction with return air slot, produces a high level of air induction to cause

rapid and complete mixing of room air.

�� Supplies uniform air distribution along the entire length of the slot (well within 10%).

�� Available in one, two, three or four slots in four diffuser lengths.

�� The T-bar type diffuser fits over T’s, eliminating the need to add or remove grid members.

�� Lower installation costs due to Carnes’ innovative design of the linear slot diffuser eliminating

50% of the tile cost.

�� Visual conformity. Linear slot diffusers and return air slots are identical in appearance.

INTRODUCTION & DESCRIPTION | Models DFSB and DFRB

INTRODUCTIONCarnes Models DFSB supply and DFRB return arefixed horizontal pattern slot diffusers for use in mostexposed T-bar ceilings. The DFSB will hold a hori-zontal air pattern at less than 10% of nominal CFM

(50 per linear foot of slot). The return diffuser ModelDFRB is identical in appearance to the DFSB toallow for complete continuity to ceiling appearance.

2 Slots — 2 Ways 3 Slots — 2 Ways 4 Slot — 2 Ways

1 Slot — 1 Way 2 Slots — 1 Way 3 Slots — 1 Way

DESCRIPTIONCarnes fixed horizontal pattern slot diffusers areavailable in 1, 2, 3 or 4 slot models, and can beordered in 24”, 30”, 48” and 60” lengths. The DFSBsupply and DFRB return diffusers are constructed of24 gauge painted formed galvanealed steel. Thebright white finish matches most ceiling T-bars andtile. The integral insulated plenum is of 24 gauge galvanized construction. The plenum insulation is1/4” - 3 lb. density fiberglass internally mounted andmatte faced to prevent erosion. The insulation meetsUL 181 and NFPA 90A requirements. Each supply

diffuser can be furnished with a 5”, 6”, 7” or 8” roundplenum inlet. The 10” inlet, when specified, has anoval configuration. The supply diffuser plenum inletcollar is 1-3/4” deep for easy flex duct connections.The return diffuser plenum is also insulated and hasopen sides to return air to the ceiling plenum. TheCarnes DFSB has an excellent air distribution pattern, no butterfly pattern. Slot velocity is uniformand sound levels are very low, giving you an efficientdiffuser with excellent performance.

SUGGESTED INSTALLATION INSTRUCTIONS | Models DFSB & DFRB

Carnes Fixed Pattern Slot Diffusers Models DFSBSupply and DFRB Return are designed to be supported by the T-bar ceiling grid system. The diffuser utilizes the “T” for control of the air distribution pattern. If T-bars with a face dimension ofless than 15/16” are used, there may be dumping ofsupply air at low CFM’s.

The two way blow units straddle the main T-bar andare either wired to the T-bars that run perpendicularto the diffuser at each end or wired to structural supports above. The methods are shown below.

One way blow units are set along side the T-bar withthe air pattern blowing away from the T-bar. The oneway blow units are supported in the same manner asthe two way units.

After the slot diffusers are installed the support tilemust be trimmed and laid on the edge of the louverto fill out the opening. No additional T-bars arerequired.
